Kenney compares Lödz, Poland's largest manufacturing center, and Wroclaw, a city rebuilt as Polish upon the ruins of wartime destruction. His account of dramatic strikes in the textile mills of Lödz shows how workers resisted the communist party's encroachment on factory terrain and its infringements of worker dignity. The contrasting absence of labor conflict among migrants in the frontier city of Wroclaw holds important clues to the nature of stalinism in Poland: communist power was strongest where workers lacked organizational ties or cultural roots. In the collective reaction of workers in Lödz and the individualism of those in Wroclaw, Kenney locates the beginnings of the end of the communist regime. Losing the battle for worker identity, the communists placed their hopes in labor competition, which ultimately left the regime hostage to a resistant work force and an overextended economy incapable of reform.
